PPBE (planning, programming, budgeting and execution) explained

PPBE is the Department of Defense process for building its budget. A 14-member commission created by Congress has proposed replacing it with a new Defense Resourcing System.

PPBE stands for Planning, Programming, Budgeting, and Execution, the Department of Defense (DOD) process for developing its budget. The Congressional Research Service (CRS) dates the process to the 1960s. Its Insight IN12372, dated May 31, 2024, says some recommendations from a congressionally created reform commission would replace the PPBE process.

That commission's final report contains 28 recommendations. The first one would swap PPBE for a new Defense Resourcing System with fewer processes. Other recommendations deal with how appropriations are structured, how money carries over between years, and what DOD can start under a continuing resolution.

Future-Years Defense Program Rules in 10 U.S.C. 221

By law, the Secretary of Defense must send Congress a future-years defense program (FYDP) every year, no later than five days after the President's budget is submitted. That requirement sits in 10 U.S.C. 221(a). The FYDP reflects the estimated expenditures and proposed appropriations in the President's budget.

Each FYDP covers the budget year and at least the four fiscal years after it. That makes every submission a view of at least five fiscal years (1 budget year plus 4 succeeding years).

The amounts in the FYDP must be consistent with the amounts in the President's budget for each fiscal year, under 10 U.S.C. 221(b). The Secretary must also make each FYDP available to Congress, the Congressional Budget Office, the Comptroller General and CRS as an unclassified electronic database. Printed copies go to the congressional defense committees, under 10 U.S.C. 221(d).

Why Congress Created the Commission on PPBE Reform

Congress created the Commission on PPBE Reform through Section 1004 of the National Defense Authorization Act (NDAA) for Fiscal Year 2022, Public Law 117-81. The law set the commission at 14 members. Its job was to examine how effective PPBE is and recommend improvements.

The commission published an interim report on August 15, 2023. Its final report, titled "Defense Resourcing for the Future", followed on March 6, 2024, a little under seven months later.

The commission's chair, vice chair and executive director testified before the Senate Armed Services Committee on March 20, 2024. That hearing came 14 days after the final report was published.

What the PPBE Reform Commission's Final Report Recommended

The final report makes 28 recommendations, some with multiple parts, grouped into five "critical areas". The report labels 14 of them as "key": recommendations 1, 2, 3, 4, 6, 8, 9, 10, 11, 17, 19, 20, 25 and 27. According to CRS, the report does not define how it chose those 14.

Three of the recommendations marked "key" are summarized below. Recommendation 1 replaces the process. Recommendation 4 reorganizes how Congress appropriates money. Recommendation 9 addresses what DOD can do under continuing resolution authority.

Recommendation 4 carries a target date. The commission aimed for adoption of the new appropriations structure in fiscal year (FY) 2027, so it would apply to the FY2028 President's budget request.

Draft Legislative Language and the Implementation Plan

The commission attached draft legislative language to four recommendations: 6, 8, 14 and 16.

Recommendation 6 and recommendation 8 are both on the commission's "key" list. Recommendations 14 and 16 are not, even though they also came with draft language.

Recommendation 28 covers putting the changes in place. It proposes a cross-functional team reporting to the Deputy Secretary of Defense, working on a "three-to-five year timeframe".

Why Industry Readers Follow PPBE Timing and Structure

Two recommendations bear directly on when and how defense money can move: recommendation 9 on timing and recommendation 8 on reprogramming. Recommendation 9 would let DOD start or accelerate certain weapon systems under continuing resolution authority. The condition is that the President's budget requested those systems and the relevant congressional committees approved them.

Recommendation 8 would raise below-threshold reprogramming thresholds and allow reprogramming of up to 1.5 percent per account. On an account of $100 million, 1.5 percent works out to $1.5 million that could be shifted under that rule.

Implementation Status of the Recommendations

CRS notes that Congress could consider some of the commission's changes in the FY2025 budget cycle. The CRS Insight is dated May 31, 2024, and it gives no detail on how any recommendation was later implemented.

This page does not track whether any of these 28 recommendations has been adopted, changed or dropped. This page reports what the commission proposed, as summarized by CRS, and makes no forecast about what Congress will do.
